What is anti-lock braking system?

ABS or Antilock Braking System usually apply and release braking pressure up to 20 times a second. it consists of a central Electronic Control Unit ECU, Four Wheel Speed Sensors and Hydraulic Control Valves. The ECU constantly monitors the rotational speed of each wheel, and when it detects a wheel rotating significantly slower than the others (wheel lock) it actuates the valves to reduce hydraulic pressure to the brake at the affected wheel, thus reducing the braking force on that wheel. The wheel then turns faster; when the ECU detects it is turning significantly faster than the others, brake hydraulic pressure to the wheel is increased so the braking force is reapplied and the wheel slows. This process is repeated continuously, and can be detected by the driver via brake pedal pulsation. This helps in controlling the vehicle while braking as the wheels doesn't lock and the vehicle doesn't slide. helps you take a turn on high speed and stop car on slippery surface in minimum distance. Recent Developments in ABS has also included electronic brakeforce distribution (EBD), traction control system (TCS or ASR), emergency brake assist (BA, EBA or HBA), or electronic stability control (ESP, ESC or DSC).|||ABS is a computer controlled braking system where the car detects if a wheel is locking up while braking. If a wheel is locking up then the car releases the pressure in that wheel's brake caliper.





The purpose of it is because you get much more traction when your tire is not sliding and when you are sliding you cannot control your direction- you just slide in a straight line.





In other words, ABS is good for you. It potentially improves braking distances and increases your control of your car.|||When driving a car without abs when you apply the brakes in a firm manor on a slick surface, the wheels will lock up and the vehicle will skid and go where it wants to even if you turn the wheels to another direction. A car with abs has a computer that will pulsate the brakes and allow the wheel to roll again instead of locking up on you, this allows the car to be able to go in the direction that you are steering the car and avoid the potential accident. without abs it is wise to pump your brake pedal to try to regain the steering, however with abs, you hold a firm brake pedal and let the computer do the work. Unless you can pump the brake pedal faster than 25 times per second, then hold a firm pedal and the computer will do that for you.|||ABS or anti lock braking system prevents the locking of tires while braking. if the tires are locked or jammed by the brakes the vehicle skids in the direction of the max. momentum. To get a firm grip on the road or ground it is necessary for the tires to move a little which is assited by ABS.
